What year is the next leap month

Leaping month is one of the ways of calendar leap. That is 1 month added in the leap year of the lunar calendar. The lunar calendar is a lunar calendar, which stipulates that a month without gas is a leap month, and the name or ordinal number of the month above is called a "leap month". Leap February in 2023 is followed by leap June in 2025.

When ancient astronomers compiled the lunar calendar, in order to make any day in a month contain the meaning of the moon phase, that is, the first day is a moonless night and the fifteenth day is a full moon, so the first day is mainly the first month. At the same time, considering the seasonal changes, they adopted the method of seven leaps in nineteen years: in the nineteenth year of the lunar calendar, there are twelve normal years and one normal year has twelve months; There are seven leap years and each leap year has thirteen months.

The current method of setting lunar leap

The current method of setting leap in lunar calendar is "19 years and seven leap years", that is, every two to three years, a lunar month that is the same as the previous month is added, and the added month is called leap month. The rules of leap method are based on 24 solar terms related to the tropic year of solar calendar. A tropical year is divided into 24 solar terms. If the twenty-four solar terms are discharged from beginning of spring to Great Cold, then the odd number is called solar terms and the even number is called neutral gas.

In the lunar calendar, twelve Chinese qi are used to represent twelve months of a year, and the average interval between Chinese qi and Chinese qi will be nearly one day longer than that of a lunar month. In the long run, there will always be a phenomenon of qi at the end of the month, so there will be no qi next month, only solar terms (that is, the next qi will be in early February of the lunar calendar). So this lunar month without neutrality is called the leap month of last month.
